Opinions?

I am 8dpo and have been experiencing sore breast (especially after wearing a bra for a few hours and after exercise. Sometimes also get a quick sharp pain in nipples), breakouts on my face, lower back pain, tiredness, slight cramping, and slight nausea. Also every night I get crazy dreams. I've been feeling this was since last week which is very unusual for me. I usually don't get pms symptoms until about 5 days before AF. Also, a couple nights ago I got a sharp pain on the right side of my pelvic area for a couple seconds and then a few minutes later got another one more towards the middle. AF is due in 7 days and I am regular. Any opinions on if I could be pregnant?
